Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail through specific embodiments and related drawings below.

As shown in FIG. 1 , a wiring rod for insulation and withstand voltage tests of substation equipment includes a clip body 1 . The clip body 1 is formed by hinged middle parts of two clips 101 . There is a compression spring 2 sandwiched between the two clips 101, and a tapered opening 102 is formed between the handles at the rear ends of the two clip bodies 1, and the hinges of the two clips in the tapered opening 102 are fixed to one end of a screw rod 3. Connecting, the other end of the screw 3 extends toward the tapered opening 102, the screw 3 is screwed with a connecting piece 4, the front end of the connecting piece 4 is a tapered portion 401 matching the tapered opening, the connecting piece 4 The rear end of the clip body is fixedly connected with the joystick 5; the two clamping parts of the front opening of the clip body 1 are respectively fixedly connected with a cantilever 6 extending forward, and the inner side of the cantilever 6 is hinged with the middle part of the semi-elliptical clamping member 7 , the rear ends of the two clamping parts 7 are hinged so that the two clamping parts 7 are clamped to form an elliptical structure. In normal conditions, under the action of the compression spring 2, the two clamping parts 7 are in an open state. 5.
